So now I have to allow registering from WAN on this site (or other workarounds I'm considering). Queries marked with a mode value of 6 are NTP Control Messages. The response will contain the NTP servers state along with a list of known peers. Crucially the response is larger than the request. When a request comes from a source which is spoofed this can be used in a DDOS attack. Seb.

These requests are added to a waiting list and processed when we recover IPv4 addresses in the future. To make an IPv4 request, you will need to become a member of the RIPE NCC. Existing members can only submit a request if they.
